Background ========== Xpdf and GPdf are PDF file viewers that run under the X Window System. Poppler is a PDF rendering library based on Xpdf code. The Common UNIX Printing System (CUPS) is a cross-platform print spooler. It makes use of Xpdf code to handle PDF files. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/xpdf < 3.01-r2 >= 3.01-r2 2 app-text/gpdf < 2.10.0-r2 >= 2.10.0-r2 3 app-text/poppler < 0.4.2-r1 >= 0.4.2-r1 4 net-print/cups < 1.1.23-r3 >= 1.1.23-r3 ------------------------------------------------------------------- 4 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== infamous41md discovered that several Xpdf functions lack sufficient boundary checking, resulting in multiple exploitable buffer overflows. Impact ====== An attacker could entice a user to open a specially-crafted PDF file which would trigger an overflow, potentially resulting in execution of arbitrary code with the rights of the user running Xpdf, CUPS, GPdf or Poppler. Workaround ========== There is no known workaround at this time. Resolution ========== All Xpdf users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/xpdf-3.01-r2" All GPdf users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/gpdf-2.10.0-r2" All Poppler users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/poppler-0.4.2-r1" All CUPS users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-print/cups-1.1.23-r3" References ========== [ 1 ] CVE-2005-3191 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3191 [ 2 ] CVE-2005-3192 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3192 [ 3 ] CVE-2005-3193 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3193 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200512-08.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
